I'm confused why CBS would have passed on this special, which was No.1 for the night. That it was a ratings success is no surprise. Her Dec 2017 50th Anniversary special, which was on CBS, had the largest total audience for an entertainment/non-sports special that year since the Oscars 9 months before.
I feel lucky to have seen Burnett and Brian Dennehy in Love Letters a few years back. A really wonderful night.
